i cant use a mouth call yet myself so i cant help there...as for decoys...i dont use them and neither does my dad and he killed a few longbeards in his day..and his calling really is nothing special...just sits there and yelps on his glass call and they seem to come running..i would say get a friction call maybe a glass or a slate or something like that if you can...i use that alot more than anything else...a box call is nice in wind but if you get good with a mouth call you can learn to scream with it...maybe a locator call like a crow call is all i use...and about the paint..i really odnt like that they sell masks out there that are alot easier and only a buck or 2 more than paint and will last forever and be easier and you wont look like a wannabe rambo in the woods lol good luck...post all your questions you will get the help!
